About this 1.59ct natural heart diamond

This 1.59ct natural heart sits in the one-and-a-half to two carat band, graded F colour (colourless) and SI1 clarity (slightly-included), with a standard cut grade stated by the retailer rather than the lab and certified by GIA 5212239450. Listed at 14 retailers as of October 30, 2026, with prices from €4,417 to €9,847, a €5,430 spread on the same certified stone. NZ Jewellers lists it at €9,847. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
